120 g ethylene glycol in 450 g liquid
a) A container was found in the home of the victim that contained 120 g of ethylene glycol in 450 g of liquid. What was the percentage of ethylene glycol?
액체 450 g에 에틸렌 글라이콜 120 g이 들어있는 용기
b) If the toxic quantity is 1.5 g of ethylene glycol per 1000 g of body mass, what percentage of ethylene glycol is fatal?
유독량이 체중 1000 g당 에틸렌 글라이콜 1.5 g

a) A container was found in the home of the victim that contained 121 g of ethylene glycol in 540 g of liquid. What was the percentage of ethylene glycol?
(120 / 450) × 100 = 26.6667%
답: 27%
b) If the toxic quantity is 1.5 g of ethylene glycol per 1000 g of body mass, what percentage of ethylene glycol is fatal?
[1.5 / (1.5 + 1000)] × 100 = 0.1498%
답: 0.15%
“용액 = 용질 + 용매” 인데,
이 문제에선
용질 = 에틸렌 글라이콜
용매 = 체중, 즉 사람
에틸렌 글라이콜이 사람 몸 속에 들어와야
용액이 형성되므로, ( 또한 이때 독성이 발생. )
용액 = 에틸렌 글라이콜 + 체중
이 조건으로 치사량을 계산한다.
